Heat transfer methods and sheets for applying an image to a substrate

摘要

Methods are generally provided of transferring an image to a substrate using a colorless fusible polymer material printed onto a printable surface of a printable transfer sheet to form an imaged area. The printable transfer sheet can be positioned adjacent to a coating transfer sheet such that the imaged area is adjacent to a meltable coating layer of the coating transfer sheet. The meltable coating layer and the imaged area can then be fused together, and the sheets separated to form an intermediate coated imaged sheet, such that the imaged area is coated with the meltable coating layer. The intermediate coated imaged sheet can be positioned adjacent to the substrate such that the imaged area coated with the meltable coating layer is adjacent to substrate, and heat and pressure can be applied. The intermediate coated imaged sheet can be separated from the substrate to leave the imaged area on the substrate.

1. A method of transferring an image to a substrate, the method comprising
printing a colorless fusible polymer material onto a printable surface of a printable transfer sheet to form an imaged area, wherein the printable transfer sheet comprises a release layer defining the printable surface and a base layer; positioning the printable transfer sheet adjacent to a coating transfer sheet such that the imaged area on the printable surface of the printable transfer sheet is adjacent to a meltable coating layer of the coating transfer sheet; applying heat and pressure at a first transfer temperature to the printable transfer sheet positioned adjacent to the coating transfer sheet to fuse the imaged area to the meltable coating layer; separating the printable transfer sheet from the coating transfer sheet to form an intermediate coated imaged sheet, wherein the imaged area is coated with the meltable coating layer; positioning intermediate coated imaged sheet adjacent to the substrate such that the imaged area coated with the meltable coating layer is adjacent to substrate; applying heat and pressure at a second transfer temperature to the intermediate coated imaged sheet; and separating the intermediate coated imaged sheet from the substrate to leave the imaged area on the substrate, wherein the imaged area left on the substrate comprises the colorless fusible polymer material on the meltable coating layer.
